"I've been working out at Tam CrossFit for about three years now and I absolutely love it. Staff is very professional and knowledgeable and the size of the box is perfect. Workouts and instructions are well designed - most days I end up on the floor panting but wanting more."

"I started at Tamalpais CrossFit a year and a half ago and can honestly say my life has changed. For the longest time I was hesitant to join - I'd heard there was such a high risk of injury. But the coaches here are so focused on form and safety. Best decision I ever made."
